OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 432,736, dated July 22,1890.

Application filed February 13, 189i). Serial No. 340,325. (No model.) i

To all whom it may concern.-

Be it known that I, DUWAYNE E. JOHNSON,

a citizen of the United States, residing at Farlington, in the county ofCrawford and State of Kansas, have invented certain new and usefulImprovements in Oil-Cans; and I do hereby declare that the following isa full,clear, and exact description of the invention,which will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to oil-cans embodying simple and improved meansfor forcing the oiltherefrom; and it has for its object to provide anoil-can of this character which will possess advantages in point ofinexpensiveness, durability, ease of operation, and general efficiency.

In the drawings, Figure 1 is a perspective view of an oil-can embodyingmy invention. Fig. 2 is a vertical longitudinal sectional view thereof.Fig. 3 is an enlarged detail sectional view of parts of Fig. 2. Fig. 4is a horizontal sectional view taken on the line m at, Fig. Fig. 5 is asimilar view on the line y y, Fig. 3, looking toward the outer end ofspout. Fig. 6 is a similar view on the line z z, 3, looking toward theoil-receptacle. Fig. 7 is a detail perspective view of the valvemechanism removed.

Corresponding parts in the figures are denoted by the same letters ofreference.

Referring to the drawings, A designates the can, which may be of anysuitable or preoil may pass.

ferred construction, and constructed of any desirable material, and isprovided with an elongated spout or tube A, having either a curved orstraight outlet end a. The can is also provided with an opening a,through which it may be filled, and with a handle a Within the spout ofthe can is disposed an outer transverse partition B, provided with aseries of perforations Z), through which the Below the partition B,betweenthe same and the can proper or receptacle, is disposed a secondtransverse partition 0, also provided with a series of perforations c,which form ports, the latter partition serving as a valve-seat. A rod Dis secured at one end centrally within the partition B, from which itprojects downwardly or inwardly through a perforation (I, providedtherefor centrally within the partition 0, the purpose of which will behereinafter set forth.

Upon the valve-seat C, between the same and the partition B, is normallyseated a valve E, of smaller diameter than the spout at this point,butof sufficient size to cover the ports in the valve-seat. The valve isnormally held to its seat by a coil-spring e, disposed between thepartitions B and C and encircling the rod D, the latter passing looselythrough the center of the valve.

F design ates a sliding piston disposed below the valve-seat O andfitting closely against the walls of the spout. This sliding piston isprovided with a central perforation f, through which the rod D works,and with a series of ports f. Upon the top of the piston F is provided aframe-work G, raised somewhat above the same and serving as a rest forthe lower end of a coil-spring H, encircling the rod D and occupying thespace between the frame G and the valve-seat C, said spring being ofgreater tension than the spring 6, and is designed to exert a downwardpressure upon the piston. The rod D also passes through the frame andserves to effect an easy movement to the piston F, as well as to retainthe coilspring H against displacement.

Upon the piston F, and between the same and the frame G, is disposed avalve I, normally held upon its seat by a coil'spring 'i, encircling therod D and disposed between the valve and the frame Gr.

For effecting the operation of the valves I provide means which I willnow proceed to describe.

J designates a rod, which projects from near the bottom of the can upthrough the spout to the piston F, to which it is secured, saidrod'being bifurcated at its upper secured end to permit of the play ofthe rod D therebetween. The rod J is pivoted at its lower end to one endof a lever L, the latter being pivoted at about its center to a standardZ, projecting from the bottom of the can. To the free end of the leveris pivoted the lower end of a rod M, which projects upwardly and througha perforation m, provided therefor in the can. The exterior portion ofthis rod is bent down and over the handle a where it is provided with athumb-piece m.

The operation and advantages of my invenleased, the spring H returns thepiston F to its normal position, during which movement the valve E isheld to its seat, while the valve 1 is raised to permit the oil to enterthe space between the valves, when the operation may be repeated.

I claim as my invention- 1. The combination, with an oil-can providedwitha spout projecting therefrom, of a stationary valve-seat carrying avalve, a sliding piston carrying a valve and working upon acentrally-disposed guide-rod, springs ing the valves and piston to theirnormal positions, all of said mechanism being contained within thespout, and means for operembracing the latter and adapted for return--2. The combination, with an oil-can provided with a spout projectingtherefrom, of a stationary valve-seat disposed in said spout andcarrying a valve, a centrally-disposed station ary guide-rod proj ecting inwardly through said valve-seat and valve, a sliding piston workingon said rod and within the spout and carrying a valve, an oil-chamberbeing formed between the valve-seat and piston, and means for operatingthe piston to eject the oil from said chamber, substantially as setforth.

3. The combination, with an oil-can provided with a spout projectingtherefrom, of a stationary valve-seat disposed within the spout andprovided with a valve, a stationary partition above the said seat, asliding piston working in the spout and upon a guide-rod, said pistonbeing provided with a valve and with an arched frame inclosing thelatter,

springs for returning the valves and piston to their normal positions,and means for oper-' ating the piston, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
